15 Claims. 1

This invention relates to a valve and one especially adapted for controlling the operation of fluid operated motors, such as window operators or other light motors operable from a source oi suction` The object of the present invention is to provide a control valve of simple and economical design which is efficient in operation and of practical utility.

The invention further has for its object to provide a control Valve for suction operated accessories for motor vehicles and the like which is of simple design and novel in its operation in that the valving member is rockable on one or the other of two axes adjacent spaced ports for opening the remote port while maintaining the near port eiectively sealed against fluid leakage.

In the drawing,

Fig. l is a plan View of the valve with portions broken away;

Fig. 2 is a vertical sectional View therethrough about on line 2-2 of Fig. 1;

Fig. 3 is a side elevation of the valve with the face plate in section;

Fig. 4 is a sectional view about on line 4 4 of Fig. 2;

Fig. 5 is a detailed perspective view of the locking ring used for securing the face plate in position; and

Fig. 6 is a sectional View partly in elevation depicting a modified embodiment of Valve actuator.

Referring more particularly to the drawing, the numeral I designates the body of the Valve having spaced ports 2 and 3 opening through a seat forming face 4 thereof. Engaging the seat is a valve 5 in the form of a soft rubber annulus with opposite portions of the ring seating over the two ports. The inner periphery of this valving ring is provided with a groove 6 which imparts thereto a cross section of U-design and denes a lower flexible flange 'l free of the plate and of a width suflicient to close both ports. The ports are arranged substantially at diametrical points, with respect to the valving ring, and therefore one side or arc of the ring may be lifted from its port while the opposite side remains in port closing position, and vice versa. To accomplish this rocking or tilting action a stili member in the form of a disk 8 has its margin or periphery engaged in the f thereby serve to lift the rubber Valving ring 'iat one side or the other to open the corresponding port, the opposite portion of the liange 'I remaining in port sealing engagement with the seat due to the resiliency of the soft rubber body of the ring. To increase this resiliency or iiexibility of the Valving flange the latter may taper inwardly, as at II, to reduce the thickness thereof. The ange l is by this arrangement anchored to the margin of the plate and extends inwardly over the latter but free thereof to provide in effect a hinge mounting from which the plate rocks while permitting the iiange, acting in the capacity of a flap valve, to remain fully seated over its port. The seat face l! is provided with a port I2 for admitting fluid at atmospheric or other pressure into the valve chamber I3 beneath the tiltable or rockable valve. Atmospheric air may be filtered by a pad It, as shown in Fig. 2, and when the valve is tilted to open either port 2 or 3 the air flow will then be out from the chamber I3 through the opened one of these ports. The ports may be connected by the nipples I5 to a suction operated motor to unbalance the same when either port isopened, the source of suction for such motor acting normally through the latter to hold the valving ring seated.

The body I is provided with a retaining rim I6 upstanding about the margin of the seat 4 so as to retain the Valving ring 5 in position on the seat.

A coil spring Il' bears upon the upper face of the disk 8 to urge the valving member to its operative position, wherein both of the suction or motor ports 2 and 3 are closed. This spring may iind bearing on the bottom wall I8 of an inverted cup shaped casing l!! telescoped over the rim i6, or a special washer 20 may be placed upon the bottom i3 for supporting the spring I'I under compression. The washer may snugly fit the stem` Q and slide on the wall i8 when the stem is rocked. Radial lingers 2l extending from the margin of the cup I9 are provided with screw receiving openings 22 for mounting the casing on a support.

A face or escutcheon plate 23 is superimposed upon the wall I8 to give a neat appearance to the installation, such face plate being retained in position by a ring 24 which has a pair of arcuate attaching members 25 extending through like shaped slots in the plate for centering the latter on the casing by telescoping the same. These members are provided with bayonet slots 26, Fig. 5, to receive the lugs 21 struck out from the casing I9. By turning the ring counterclockwise or clockwise the face plate may readily be secured in place or demounted as the occasion may require. The face plate and the wall I8 areformed with registering slots 28 through which the actuating stem 9 projects, the elongation of the aperture defining the direction of tilt for the valve to uncover one or the other of the suction or motor ports 2 or 3. The slot in the wall I8 will be closed by the washer 20 to exclude dust and dirt from entering the casing. The retaining ring 24 may be rmly united to the facing platekby bending the lugs 329 voutwardly over the back :face ,of 7the plate which is formed with recesses"30 to receive the lugs.

By simply rocking the knob I up or down the valving ring will be caused to tilt on the seat and lift one side from the selected port to open it to the atmospheric port :I2',";the^1ow` side of the ring maintaining its port sealing engagement with the seat by reason olf the .flexibility .of the flange 1. The construction is of simple and practical design enabling the valve to Ibe "produced economically. The provision of the flexible sealing flange-on Athe underside of the rocking disk enables one portion fof ythe -flange to remain operative when'the-opposite portion is lifted-from the seat.
